Polyculture of Giant Freshwater Prawn, Macrobrachium rosenbergii and Nilem Carp, Osteochilus hasselti Cultured in Recirculation System Using Biofiltration

Abstract

Giant Freshwater Prawn is one of the freshwater commodity which have an economy value where Nilem carp has also potentially to be cultured to produce fingerling size as a “baby fish”. The purpose of this experiment is to determine the optimal survival, growth, FCR, and productivity of Giant Freshwater Prawn and Nilem carp cultured on polyculture system and also biomass productivity of bio filter (snail, water spinach, and Cabomba). The different stocking density of Nilem carp as a treatments were as followed: A) 25 fish m-3 B) 50 fish m-3, and C) 75 fish m-3. Density of Giant Freshwater Prawn was 20 individuals m-3 for all treatments. The result showed that the optimal of survival, growth (length and weight), productivity and FCR for Giant Freshwater Prawn was found at density of 25 fish m-3 (A) than that of density 50 fish m-3 (B) and 75 fish m-3 (C) (P<0.05). The highest of biomass productivity of bio filter (snail, water spinach, and Cabomba) was found at density of 25 fish m-3 (A) than that of density of 50 fish m-3 (B) and 75 fish m-3 (P<0.05). Water quality such as DO, temperature and pH showed almost the same at all treatments.

The Feasibility of Monoculture and Polyculture of Striped Catfish and Nile Tilapia in Different Proportions and Their Effects on Growth Performance, Productivity, and Financial Revenue

“…SGR values in the present study surpass other previous experiments on striped catfish [32,33]. The present findings reveal that the relations between cultivated striped catfish with Nile tilapia in a polyculture system, growth and yield parameters are in close agreement with many reports on other catfish species, as tilapia comes after striped catfish in growth performance [10,[34][35][36][37].…”

A prototype pond water management system (dissolved oxygen, pH and temperature) for giant freshwater prawn farming in Pak Phanang, Southern Thailand

“… [ 36 ] The experiment was conducted in a rectangular concrete tank for a duration of 120 days, with the water quality parameters including dissolved oxygen, pH, and temperature being monitored and controlled. [ 42 ] A cylindrical tank made of polyethylene fabric with a thickness of 0.7 mm and a diameter of 6 m, and a depth of 70 cm was used. Factors affecting the growth of freshwater prawns in the prototype pond were controlled by implementing an intelligent water management system.…”

Enhancing Reproductive Performance of Nilem Fish (Osteochilus hasselti) through Artificial Spawning

“…An optimal temperature for fish life in tropical areas ranges between 25 and 30⁰C. Several studies indicated that Nilem fish can thrive well at temperatures ranging between 18 and 28⁰C [9,27,28].…”
